Application filed Jane 1, 1915. Serial No. 31,627.

To all whom it may concern Be it known that I, EVERETT L. BLAKES- LEE, acitizen of the United States, residing at Portland, in the county ofMultnomah and State of Oregon, have invented certain new and usefulImprovements in Paraiiining-Machines, of which the following is aspecification.

The object of my invention is to provide a device that shall deposit anextremely thin, evenly distributed film of parafiin upon any smallobject, and I accomplish said object by means of the Constructionillustrated in the accompanying drawing, which therefore becomes a partof this application for Letters Patent, and in which Figure 1 is alongitudinal section of a machine embodying my invention. Fig. 2 is anenlarged detail longitudinal section of a portion of the entrance tubeshowing the guard wire construction. Fi 3 is a transverse section online D.-D 0 Fig. 2. Fig. 4 is a transverse section of the dischargepipe, taken on line EE of Fig. 1. Fig. 5 is a transverse section of aportion of the discharge pipe on an enlarged scale.

Like characters of reference indicate like parts throughout the severa1views of the drawing.

. The entrance pipe is composed of an outer cylindrical wall, a, and aninner cylindrical wall I), the two walls forming a water-tight jacketfor hot water, and being connected eater d of ordinary construction. Theentrance pipe is mounted upon a parafiin kettle composed of an outerwall e, and an inner wall 7', the two walls forming a water-tight jacketfor hot water, and being connected by pipes c and c to a water heater dof ordinary construction. Within said paraifin kettle is a receptacle g,and intermediate said receptacle and said parafiin kettle is a pump h,of ordinary construction, and adapted to pump liquid paraflin from saidkettle into said receptacle, said pump being operated from anyconvenient outside source of power.

Communicating with the lower end of the entrance pipe is a dischargepipe 7:, said discharge pipe extending downward a d outward through theparafiin kettle, a d having at-its outer end a weighted trap door Z,adapted to open and discharge a predetermined weight of finishedproduct. Said discharge pipe is provided with an orifice m, located overthe receptacle 9, and adapted to receive the discharge end of anatomizer n, said atomizer being operated by compressed air' suppliedfrom an outside source through pipe 0, said pipe being provided withcoils submerged in the melted paraflin contained within the kettle, forthe purpose of heating the air previous to delivery to the atomizer.

Provision is made. for draining surplus paraffin out of discharge pipe70 into the kettle as follows :A crescent-shaped dam 79 is insertedtransversely in pipe is, as shown in Fig. l,'and immediately to therearward of said dam is located a transverse slot 1' in said pipe.Rearward of said slot are a plu rality of orifices 1' and immediatelyabove said orifices and said slot are located a plurality of wires, saidwires being made fast to pipe is at s, and'also to dam 79, solder orother convenient method of fastening said wires being used.

In order to prevent the product being paraflined from contacting withthe side I) of the entrance pipe, a plurality of wires 6 are placedlongitudinally within said pipe, said wires being secured (by solder orother convenient means) to annular bridges 4), located at top and bottomof said pipe, the inside diameter of the bridge at the bottom beinglarger than the outside diameter of discharge pipe is, for the purposeof allowing the paraffin to drain off of wall 7) into the kettle withoutpassing through the discharge pipe.

Bumpers w are secured at irregular intervals to wires t for the purposeof interrupting the straight passage of the product through the entrancepipe, and to cause said product to turn and twist in its descent throughsaid pipe. Said bumpers are constructed of wire bent to form an angle,the two ends of which are secured to wires 25 by a twist about same,said ends being then bent away from each other and formed to contactwith the wall I) of the entrance pipe, thereby preventing the bumperfrom rotating about the wire 25, as shown in Figs. 2

and 3.

The formed product entering the entrance pipe passes downward throughsaid pipe filled with hot paraffin vapor from atomizer .n, and intodischarge pipe [7, whence it is discharged when a sufficient weight hasaccumulated to actuate the weighted trap Z.

Having described and illustrated my invention so that others skilled inthe art may be enabled to construct and use the same, what I claim asnew and desire to secure by Letters Patent, is

1. A paraflining device comprising a heated entrance tube, a heatedmelting kettle. beneath said entrance tube, a receptacle Within saidkettle, a pump intermediate said kettle and said receptacle, adischarging tube communicating with the lower end of said entrance tubeand intermediate said entrance tube and said receptacle, saiddischarging tube extending outside said kettle, and an atomizer withinsaid receptacle communicating with said discharging tube by means of anorifice therein, said orifice being substantially upon the axis of saidentrance tubefand said atomizer being parallel to said axis.

2. A parafiining device comprising a' vertically disposed entrance tube;a heating kettle communicating with the lower end of said entrance tube,and adapted to contain liquid paraffin; means within said heating kettleto force a continuous vertical spray from said liquid parafiin upwardwithin said entrance tube; a discharging tube leading from said entrancetube to a point exterior of said kettle; a dam within said dischargingtube; said discharging tube having orifices adjacent said dam andconnecting with said kettle.

3. A paraffining device having a coating chamber, a plurality of wiresannularly arranged within said coating chamber and a small distanceWithin the inner wall of same, each of said wires extendinglongitudinally throughout said chamber, and bumper pieces secured tosaid wires.

4. In a device for parafiining articles, a coating chamber; a pluralityof guards secured within said coating chamber, said guards beingdisposed so as to prevent contact between said articles and said chamberas said articles are passing therethrough, and bumper pieces secured tosaid guards.

5. A paratfining device having a discharge pipe, a dam within saiddischarge pi c, said dam covering only a small portion of the internalarea of said pipe, orifices in said pipe, said orifices being locatedupon one side of and adjacent to said dam, and a plurality of wireswithin said pipe adjacent to e d orifices, said wires being attached atone end thereof to said dam, and at the opposite end thereof to saidpipe, said orifices lying betweenthe opposite points of attachment ofsaid wires.

In witness whereof I claim the foregoing as my own, I hereunto afiix mysignature in the presence of two subscribing witnesses.
